Which process takes the most energy? a.) Heating 10 kg of ice to the melting point. b.) Heating 10 kg of water to the boiling point. c.) Melting 10 kg of ice at a constant temperature. d.) Turning 10 kg of water to steam at a constant temperature. e.) None of the above.

d.) Turning 10 kg of water to steam at a constant temperature.

Explanation:

Heat energy is the energy absorbed or released by a body or an object due to temperature difference. It flows from a body or system of higher temperature to that of lower temperature.

When heat energy is applied to change the state or phase of an object, a lot of energy is required in the process. The major two types of heat flow involved for the process are: specific heat and latent heat.

Therefore in the given question, the process that requires most energy is turning 10 kg of water to steam at a constant temperature.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
